An updated version of Battlefield 3: Back to Karkand will be available today on PS3, developer DICE has announced.

Rather than issue a patch, Back to Karkand players will need to re-download the entire add-on, but this will be free of charge.

"Note that changes made on our back end will make this re-download mandatory in the near future," explained DICE in a blog post made yesterday. "If you buy Back to Karkand for the first time after tomorrow, no additional action is necessary."

The new version of Back to Karkand fixes the weapon animation bug which some users have experienced.
